Do shared S-minus functions among stimuli lead to equivalence?

Do shared S-minus functions among stimuli lead to equivalence?

Date: August 2005
Creator: Kassif-Weiss, Sivan O.
Description: We examined the claim that equivalence classes contain all positive elements in a reinforcement contingency by asking whether negative stimuli in a reinforcement contingency will also form an equivalence class, based on their shared function as S-minus stimuli. In Experiment 1, 5 subjects were tested for equivalence for positive and negative stimuli. Testing of positive stimuli preceded testing of negative stimuli. Two of five subjects demonstrated equivalence for positive stimuli, and three subjects demonstrated equivalence for negative stimuli. In Experiment 2, order of testing was reversed. Four of six subjects demonstrated equivalence for positive stimuli, and none demonstrated equivalence for negative stimuli. In Experiment 3, positive and negative stimuli were tested together. Only one of five subject demonstrated equivalence for positive and negative stimuli. These data suggest that negative stimuli may enter an equivalence class, and so Sidman paradigm should be expanded. Order of testing was found as a meaningful variable.

Does Family Quality of Life Change? Evaluation of a Group Parent-coaching Package

Does Family Quality of Life Change? Evaluation of a Group Parent-coaching Package

Date: December 2012
Creator: Wiles, Amber Marie
Description: Improving family quality of life is an important goal when working with families of children with autism. Researchers have attempted to measure changes by developing indices of quality such as affect, stress, and confidence. The purpose of this study was to examine the effects of a group parent-coaching program on measures aimed at addressing quality: a) parent confidence, stress and affect ratings; b) child affect ratings; c) the frequency of coordinated joint attention (CJA); and d) parent report of satisfaction and efficacy. Over the course of four weeks, the coaching program involved group presentations, discussions, video sharing, and problem solving, and individual in-vivo coaching sessions regarding specific child skill development. Results from the five parent-child dyads suggested increases in areas associated with quality of life. Results are discussed in the context of quality themes and mixed methods research.

Does stimulus complexity affect acquisition of conditional discriminations and the emergence of derived relations?

Does stimulus complexity affect acquisition of conditional discriminations and the emergence of derived relations?

Date: December 2009
Creator: Martin, Tiffani L.
Description: Despite the central importance of conditional discriminations to the derivation of equivalence relations, there is little research relating the dynamics of conditional discrimination learning to the derivation of equivalence relations. Prior research has shown that conditional discriminations with simple sample and comparison stimuli are acquired faster than conditional discriminations with complex sample and comparison stimuli. This study attempted to replicate these earlier results and extend them by attempting to relate conditional discrimination learning to equivalence relations. Each of four adult humans learned four, four-choice conditional discriminations (simple-simple, simple-complex, complex-simple, and complex-complex) and were tested to see if equivalence relations had developed. The results confirm earlier findings showing acquisition to be facilitated with simple stimuli and retarded with complex stimuli. There was no difference in outcomes on equivalence tests, however. The results are in implicit agreement with Sidman's theory of stimulus equivalence.

Easter Seals North Texas Autism Treatment Program Evaluation: Child Progress

Easter Seals North Texas Autism Treatment Program Evaluation: Child Progress

Date: May 2010
Creator: Brunson, Lashanna Yvette
Description: This study reports and evaluates child outcome measures at a non-profit autism treatment program providing applied behavior analysis (ABA) based services to children age 3 to 8. To accomplish this, a review was conducted of available outcome data for a 1 year period. Several categories of outcome measures have been reported in the autism treatment literature (post-intervention educational placement, cognitive status, developmental and achievement status and/or progress, autism symptom reduction, and diagnostic reclassification). This study found that the program relied on 2 sources of data to evaluate child outcome: Hawaii Early Learning ProfileĀ® and program goal mastery. Children are making progress as indicated by these measures. The findings are discussed in relation to broader outcome recommendations.

Effect of a stimulus shaping procedure on fluent letter sound acquisition.

Effect of a stimulus shaping procedure on fluent letter sound acquisition.

Date: August 2009
Creator: Maxwell, Larisa Ann
Description: Numerous studies have evaluated and confirmed many benefits of errorless learning and fluency-based procedures. The purpose of this study was to evaluate the benefits of combining an errorless learning procedure, stimulus shaping, and fluency-based procedures to teach see/say letter sound discriminations to three preschool children. Participants were taught 6 letter sounds using a hear/point stimulus shaping procedure followed by a see/say fluency-based procedure. A second letter set was taught using only the fluency-based procedure. Results showed that combining the procedures reduced the amount of teaching time by up to 40% and the percent of errors by up to 50%. This preliminary evidence shows exceptional promise in application of this combination of procedures to teach letter sounds to preschool children.

The Effect of High-Probability Request Sequences on Latency to Comply with Instructions to Transition in a Child With Severe Mental Retardation

The Effect of High-Probability Request Sequences on Latency to Comply with Instructions to Transition in a Child With Severe Mental Retardation

Date: December 2010
Creator: Carpentieri, Michelle Lee
Description: This study investigated the effect of implementing high-probability request sequences prior to the delivery of instructions to transition in a child with severe mental retardation. Data were collected on latency to comply with a low-probability request to transition and a modified version of the low-probability request. Implementation of high-probability request sequences resulted in shortened latencies to comply with the modified low-probability request instructing the child to engage in a preferred activity located at the endpoint of the transition.

Effect of Resource Availability on Dyadic Fitness

Effect of Resource Availability on Dyadic Fitness

Date: August 2010
Creator: Neves, Ana Barbara Vieira Sinay
Description: College students participating in dyads played a game designed as an analog of early hunters whose survival, as a dyad and ultimately individually, depend on rabbits they hunt. Dyadic fitness was defined as both participants being able to hunt and it was measured by the proportion of trials in a condition that both participants hunted. The effects of scarcity (alternating rich and poor conditions) on dyadic fitness were examined in two experiments. First experiment results did not show a difference in dyadic fitness as a function of the independent variable. The second experiment increased the number of hunting seasons and also the discrepancy between scarcity in rich and poor seasons. Second experiment results show that dyads start fit in rich seasons and become increasingly fit in poor seasons. External variables could not be ruled out; therefore, additional experiments still need to be carried out to clarify results.

The effect of response preclusion on stereotypy and play in a child with autism.

The effect of response preclusion on stereotypy and play in a child with autism.

Date: December 2004
Creator: Delgado, Veronica
Description: This study investigates the effectiveness of response preclusion on stereotypic behavior (climbing and licking) and on play for a child with autism. Data were collected on stereotypic responses, play behavior, and the types of play materials the participant contacted. Implementation of response preclusion was followed by both a decrease in stereotypic behavior as well as an increase in play behavior. Play behavior did not return to baseline levels of responding during reversals to baseline, and stereotypic behavior decreased across reversals. These results suggest the current antecedent manipulation not only reduces stereotypic behavior, but also can establish an environment that is more conducive to learning new, desired behavior.

The Effects of a Communication Training Workshop on the Verbal Behavior of Caregivers

Date: August 2010
Creator: Blell, Zainab D.
Description: This study evaluated the effectiveness of a workshop designed to train adults to use supportive verbal behavior during distressful situations. Participants were trained to provide descriptive, empathetic and hopeful statements using instructions, rationales, modeling, role-play, feedback, and rehearsal. A pre-post design was used to analyze the effects of the training on verbal and non-verbal behaviors of four females during simulation scenarios. Results indicate all four participants provided maximum support statements above pre-training levels during post-training simulation and written assessments.

The effects of a conflicting instruction on a FR 5 performance

The effects of a conflicting instruction on a FR 5 performance

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Koremura, Yuka
Description: The purpose of this experiment was to evaluate the effects of a conflicting instruction on FR-5 performances by an ABABC design. After all four college students were consistently pressing 1-5-3 followed by sound-clips, the schedule value changed to FR-5 (A). Then they were presented with the written instruction "Press 426" (B) in addition to the previous condition. In the last condition (C), 1-5-3 responses were then scheduled for extinction in three participants and the reinforcer was changed from sound-clips to points for one participant. The results showed that unlike previous experiments, instructions did not override the scheduled contingencies. Instruction-following occurred only when there were no other contingencies (i.e., extinction of 1-5-3) or the scheduled reinforcer for FR-5 performances was weak.
